Can't delete way+nodes with 0.6 (JOSM)

Description

I tried deleting a way through JOSM on the 0.6 API
This was with josm (1137):

The upload seemed to fail on closing the changeset. The output from JOSM is below. It looks like the server is closing the connection (which is why I am filing this against the API vs JOSM, feel free to move it if I am mistaken)

I also tried manually committing changeset 55 through wget but was unable.
